How this service works
Check inbox status and expiry
Output
Returns the current status of the inbox (active/expired) and its expiry date for the given username on stableemail.dev
Example use cases
Verify inbox before sending emails
“Before I send that important message through my StableEmail account, can you quickly check if my inbox is still active? My username is 'marketingteam2024'.”
Monitor temporary email expiration
“I've been using this temporary StableEmail inbox for testing. Can you tell me if it's expired yet or how much time I have left? Username is 'testbox_alpha'.”
Validate client inbox availability
“One of our clients mentioned they're using a StableEmail inbox for our service integration. Can you verify that their inbox with username 'clientaccount_01' is still valid and active right now?”
Technical details
Endpoint
GEThttps://stableemail.dev/api/inbox/status?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to check whether a StableEmail inbox is still active or when it expires, before attempting to send or receive mail through it. Prefer this over the general brand docs when you have a specific username and need a programmatic status response.
Side effects
- Username not found — inbox does not exist for the given username
- Missing required username parameter — returns validation error
- Service unavailable — upstream API unreachable
- Inbox already expired — returns expired status with past expiry date
